To all whom t may concern.: l

Be it known that I, HARRY LrrvAK, citizen of the United States, and resident of the city of Hudson, in the county of Columbia and State of New York, have invented 'i certain new and useful Improvements in Folding `Beds, 'of which the following is specification.

for bed springs. More particularly, this -invention relates to a device for positioning and tensioning a bed spring on a bed stead. VOne object thereof isl to provide 'a device of the character described adapted to position the bed spring in place on the bed.

Another object is to provide a device of` the character described adapted to tension the bed spring for the taking upv of any slack or sag. Y c.

Other objects of this invention will be in part obvious and in part hereinafter pointed out. y

The invention accordingly consists in the features of' construction, combinations'bf elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope' of invention will be indicated in the following claims. K

In thev accompanying drawings, in which Ais shown one of various possible illustrative embodiments of this invention, y

Figure l is a side elevational view of a folding bed embodying this invention with the spring in placefthereon and the device for placing and tensioning the same on the bed attached thereto;

Fig. 2 is a partial-planV view correspondingto Fig. 1;

Fig. 3 is an enlargedpartial side elevational view showing the tensioning and positioning mechanism fon the spring;

Fig.,4 is an end elevational view of the folding bed shown in Fig. 1.. y

Referring in detail to the drawing, the

embodiment of the invention there shown as attachedto a bed comprising .two pairsv of end posts 10 having leg portions 11. Se-

cured to these end posts as' by means of the removable bolts 12 provided with wing nuts 13 are a pair of side rails 14. A bottom cross piece 20 is secured as by'lmeans of bolts 21 to each pair of end posts 10 beneath the side rails 14. A similar top crosspiece 23 is secured at the top of each pair of end posts. Extending between the end pieces vand over the side, railsis the usual wire springf-24 which is secured inV position andtensioned'in va manner ynow to be described by means of 'my novel apparatus.l

Detachably' secured, preferablyat each l.

end of the bed, is a housing 25 in which is assembled the mechanism for drawing the.'

saine. rlhe four, housings are secured in f Spring 0I! to the bed and tensioningl the This invention relates to a tension device the forni shownin the drawingboth tothe side rails as by theremovable bolt 26 andf nut 27'thereof, and tothe end posts by .means'of the removable bolts 28 and wing nuts'28. The mechanism comprises ashaft 29 extending cross-wise of the bed journaled as atl'30 in theV pair of opposedhousings 25,` u

secured to each pair of the end posts as shown inrFig. `4.l Mounted on this shaft is y a gear 31 and a ratchet wheel 32. A pawl 33 is suitably pivoted as at 34 in operative relation to this ratchet wheel. nothershaft V35 similarly journaled in thel pair of .op-

posed housings 25 to extend parallel tothe* shaft 29 is provided .with a handlev 36'and` carries a gear 37 arranged and" adapted to mesh with the gear 31. A; pawl 38 suitably pivoted as at 39 is. provided for this gear 37. A spring 40 provided in connection with each ofthe shafts 35 is secured at one end as at 41 to each of the side rail-s `.14,while itsv free end issecured to the shaft35 as at 42 by v means'hof a flexible connectionsuch as a chain or cord 43 passing into each lhousing-.`

The Ashaft 29 is provided with pins 44 ,adapt-1v ed to engage the mesh of the wire spring 24.A .i .f The operation of the device in practice is as follows: The Shaftl35 'is first revolvedthus winding thereon the kchains 43 against the tension of the springs 40. `When the springs 40 have lbeen fully extended the pawl 33 is allowed to drop in place in the ratchetv wheel 32 Athuspreve'ntingithe unwinding of the chains, and holding stationary the gearsV 31 on the shafts 29. The bed spring is then attached to shaft 29 in the mannerv described and the pawl'33 lifted'thusreleasing thegear v 31 which now rotates in` a direction opposite to the direction in which shaft 29 has been vi operated by lreason of the return action of the springs 40. The shaft 35 in turn rotates in the same direction as the shafts 29 being driven bythe gear wheel 37 which meshes with the gear wheel 31, and thus windingV the spring' on the shafts 29 and tensioning the same. TheV pawl 38 may be dispensed with but is preferably provided as an eXtra check t0 prevent univinding of the shafts 35 before the bed spring' has been secured to the shafts 29.

It will thus be seen that there is provided apparatus in which the several objects of this .invention are achieved and which is Well adapted to meet the conditions of practical'use;

As various -aossible embodiments might be posts, a shaft `journaled transversely'of said side rails Within said liousiiig,'nieans for operating said shaft, and atensioii device in connection with ksaid shaft adapted to be energized by the operation of said shaft as and for the purpose herein specified.
